Where would I find the last two episodes. I would have given this a 5 star had it had the last 2 episodes.

Were you to visit the website of the Science Monster you would have access to many more surviving episodes of this old time juvenile sci-fi adventure serial which---like the Buster Crabbe MOVIE serials---were based on Philip Francis Nowlan's now classic novel ARMAGEDDON 2419 A D originally published in 1928. You would learn that Captain Rogers' parents didn't christen him "Buck" but "Anthony."

And you can find this book and its sequel THE AIRLORDS OF HAN by the same author HERE:

The shows are okay.

These are 12 of what are apparently the only 14 recordings of the Buck Rogers Old Time Radio series in existance today. These 12 however are probably the crispest, best recordings available. They EQ nicely, are rather treble heavy, but have a clarity most versions don't. I wouldn't want to listen to these straight up because of the hiss, but after EQing out the uppermost bands they sound great.
These 12 episodes exist under another Buck Rogers category on Archive, along with the remaing 2 episodes available. These are the superior set of 12 between the 2.
Do yourself a favor and just grab the zip file.
